Fibremaxxing fitness trend spreads

WIONews and other social accounts circulated posts on May 18 and May 19 describing “fibremaxxing” as the latest fitness and nutrition trend, using the term for a push to increase daily fiber intake through foods such as legumes, whole grains and vegetables. Forbes reported earlier this month that TikTok creators and celebrities including Danielle Fishel and Lance Bass had also been promoting “fibermaxxing” online. (wknofm.org) WKNO-FM, in a May 18 item drawn from NPR reporting, said health experts were broadly supportive of the idea with qualifications. (wknofm.org) The core message across medical centers and dietitians was consistent: most Americans do not get enough fiber, but a rapid jump in intake can cause digestive problems if people try to “max out” too quickly. (mcpress.mayoclinic.org) ### Why are people suddenly talking about “fibremaxxing”? Forbes reported on May 3 that TikTok users had been using the hashtag to encourage followers to maximize fiber intake, framing it as a wellness upgrade with digestive and weight-management benefits. UCLA Health said the term is one of several nutrition trends that have circulated on social media, but called this one closer to mainstream dietitian advice than many fad diets. (forbes.com) UCLA dietitian Yasi Ansari said “fibermaxxing” is essentially an encouragement to increase fiber intake, something many people actually need to do. Mayo Clinic dietitian Tara M. Schmidt said the trend is about trying to meet, and often exceed, daily fiber recommendations. (wknofm.org) ### What are experts saying the benefits actually are? WKNO-FM quoted Hannah Holscher, a professor of nutrition at the University of Illinois Urbana-Champaign, saying adequate fiber intake helps reduce the risk of obesity, cardiovascular disease, type 2 diabetes and certain cancers, especially colorectal cancer. CDC guidance similarly says fiber can help prevent constipation and offers broader health benefits, particularly for people with diabetes or prediabetes. (forbes.com) Mayo Clinic and Harvard Health both describe fiber-rich foods as helping with fullness and digestive regularity. Mayo Clinic said fruits, vegetables, grains, beans, peas and lentils all contribute toward daily fiber goals. (uclahealth.org) ### Which foods are showing up most often in this trend? Mayo Clinic’s high-fiber food guidance lists beans, peas, lentils, fruits, vegetables and whole grains as core sources of fiber. UCLA Health and ColumbiaDoctors described the safest version of the trend as adding more fiber through whole foods rather than chasing extremes. The foods most often cited in coverage of the trend are practical staples rather than specialty products: legumes, oats and other whole grains, vegetables, fruit, nuts and seeds. (wknofm.org) That overlaps with standard medical guidance rather than a branded diet plan, according to the hospital and clinic explainers reviewed. (mayoclinic.org) ### What are the cautions behind the hype? ColumbiaDoctors said “fibermaxxing” should not be about “maxing out,” warning that a sudden jump from very low to very high fiber can bring bloating, gas and digestive discomfort, especially without enough water. Mayo Clinic and UCLA Health gave the same advice: increase fiber gradually and stay hydrated. (mayoclinic.org) University Hospitals said most Americans get only about half the recommended daily fiber amount, but added that “more” is not automatically “better” if the increase is abrupt. That caution is the same one repeated in the May 18-19 coverage that pushed the trend into wider circulation. (mayoclinic.org) ### What should readers watch next? Forbes, Mayo Clinic and UCLA Health have all published recent explainers as the term continues to circulate across TikTok and X in May. WKNO-FM’s May 18 report and follow-on health coverage are likely to remain the clearest markers of whether the trend stays in the fitness conversation or settles into standard nutrition advice.
